Is that Whula Whoops or Whoops of fire Shaun?
That track feature looks ok, will be borrowing someone elses SCT to test driving it of race control roof... if it survives then i'll get building!
Agree with walls of death, they look much more impressive then the fun given from driving them... unless its a 20ft high one...
Once saw a XXT drive the full length of an indoor venue on the wall above straight... was by accident and couldn't be replicated but was awesome to see!
